Answer:
Step-by-step explanation:
D = Donuts
B = Brust cut
P = Profit
B - 12D = $3
12D = $12 a donut, used $3 since it didnt say more than 3.
Plug it in
B - 12(10) = $3
B - 120 = 3
+120 +120
B= $123
If Brust had 1/4 of the profit, do 4B to find profit
4B = P
4(123) = P
P = $492
Algebros made $492 selling fidget spinners.
The minimum possible profit for Algebros would be $60
What is the general equation of a Straight line inequality?An inequality in mathematics compares two values or expressions, showing if one is less than, greater than, or simply not equal to another value. The general equation of a straight line inequality is -
[y] < [m]x + [c]
[y] > [m]x + [c]
[y] ≥ [m]x + [c]
[y] ≤ [m]x + [c]
where -
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line inequality can be also written as -
Ax + By + C > 0
By > - Ax - C
y > (- A/B)x - (C/A)
Given is Brust who took his cut (one-fourth) of the Algebros profit from selling fidget spinners to the store and bought 10 donuts for $12. He came home with more than $3.00.
Assume that Algebros had made $x profit. Then, we can write the inequality as -
x/4 - 12 > 3
On solving, we get -
x/4 > 15
x > 60
Therefore, the minimum possible profit for Algebros would be $60

Evaluate.
(w2x−3)÷10⋅z when w=−9, x = 2.7, and z=−25
Enter your answer as a simplified mixed number in the box.
Answer:
-539.25
Step-by-step explanation:
(w^2x−3)÷10⋅z
w=−9, x = 2.7, and z=−25
((-9)^2*2.7−3)÷10⋅(-25)
Parentheses first
The exponent in the parentheses
(81*2.7−3)÷10⋅(-25)
Then multiply
(218.7−3)÷10⋅(-25)
Then subtract
(215.7)÷10⋅(-25)
Now multiply and divide from left to right
21.57*(-25)

Answer:

Scale Factor = 2
Reason:
Since, B is a scaled copy of A it's corresponding sides must be in proportion with that of A, and that proportion would be its scale factor.
I held their horizontal sides and compared them.
in case of A, the side is 2.5 and in case of B it's 5.
so, 5 divided by 2.5 gets you 2, that is the scale factor.
b.3, 5 (from left to right)
Solution:
[tex] \boxed{ \mathsf{ \frac{crsp. \: side \: of \: b}{crsp. \: side \: of \: a} = scale \: factor }}[/tex]
this also means
[tex] \boxed{ \mathfrak{crsp. \: side \: of \: b =( scale \: factor) \times \: crsp. \: side \: of \: a }}[/tex]
Scale factor = 2Using this we'll get the answer to the question marks
The corresponding side to 1.5 is the vertical one in B.=> corresponding side in B = 2 × 1.5
= 3
(this is the first question mark in order from left to right)
The corresponding side to 2.5 is:= 2 × 2.5
= 5
c.53° and 37° (from top to bottom)
Solution:
Scaled shapes have the same angle measures.
Reason:
When we scale two line segments meeting at a point, the lengths of the segments change but they still are part of the same pair of rays making the same angle.

First calculate the Subsets for set, then calculate the number of proper subsets {10,19,5,0}
The subsets of {10, 19, 5, 0} are
{ } - the empty set, or 1 subset of size 0
{10}, {19}, {5}, {0} - 4 subsets of size 1
{10, 19}, {10, 5}, {10, 0}, {19, 5}, {19, 0}, {5, 0} - 6 subsets of size 2
{10, 19, 5}, {10, 19, 0}, {10, 5, 0}, {19, 5, 0} - 4 subsets of size 3
{10, 19, 5, 0} - 1 subset of size 4
A proper subset of a set is any subset of that set that is not equal to that set. The only subset that is not a proper subset is {10, 19, 5, 0}, since that's the set itself. So there are 15 proper subsets.
In general, a set of size n has a total of 2ⁿ subsets, and 2ⁿ - 1 proper subsets.
